Molecules in the gas state move much faster than their liquid or solid states. Depending on the temperature and pressure, molecules can exist in three states: gas, liquid, o â¦ r solid. At high temperatures and low pressures, the gas state is favored.
I have been told that if you start using synthetic lube oil, you must continue. Going back to regular oil will damage the engine. That does not make sense to me.
Consequently, it should make no difference if a conventional oil or synthetic oil is used for the initial break-in. The deciding factor would be the cost of the oil itself. Many late model engines are factory-filled with multi-viscosity 5W-20, 5W-30 or even 0W-40 synthetic or synthetic-blend oil from the start, and may not specify the first oil change for several thousand miles.
